i am not sure if this is the right places to report this issue. I find my surface pro X won't be able to receive SMS with its default QUALCOMM LTE modern after updating the latest windows 10 update. After un-install the update on 1/july/2021, I am again able to receive SMS with the windows default messaging app.
here is the update screen shot makes the SMS function disabled. after un-install KB5003637 and KB5003254, the SMS function works again. I have posted similar question on microsoft community, but not get a reply yet.
the update before 1/july/2021 is system default from manufacturer.
